Rear Air Suspension Shock For Land Rover Discovery 3 Range Rover Sport RPD501110 RPD501111

Q1: Is RPD501110 the left or right rear unit? The customer listing marks it as Rear without a side. It says that RPD501110 or RPD501111 are universal.

Q2: Which vehicles does this fit? Per the customer's product family, this is the rear unit matching the Land Rover Discovery 3 (2005–2009) / Range Rover Sport (2005–2012) rear Electronic Air Suspension (EAS). Confirm model, year, equipment and the original part number by VIN before ordering.

Q3: How do I confirm fitment for my car? Check by VIN in a Land Rover EPC catalog, or read the part number on the original unit and confirm it matches RPD501110 (or its counterpart RPD501111 for the other side).

Q4: Is this the complete strut assembly? Yes. It is the complete rear air suspension shock / strut — air spring bellows and shock absorber integrated into one unit, with the air fitting ready to connect. Direct replacement of the original unit.

Q5: Do I need to replace both rear sides at the same time? Same-axle pair replacement is strongly recommended. An old unit on the other side causes uneven ride height and leveling behavior, affecting handling and comfort.

Q6: My vehicle has EAS height adjustment — does this fit? Yes, this unit is designed for the EAS (Electronic Air Suspension) system on D3 / RRS. After installation, perform the suspension height calibration / system reset so the vehicle relearns the correct ride height.

Q7: How do I know the rear air shock is failing? Common symptoms: ① the rear sags or settles overnight; ② the air compressor runs frequently or for long periods; ③ a "Suspension Fault" / ride-height warning on the dash; ④ knocking or harshness from the rear while driving. Replace as soon as possible once these appear.

Q8: What should I pay attention to during installation? ① Jack up the vehicle and release air suspension pressure per the workshop manual (use the height lowering / pressure release procedure); ② disconnect the air line carefully and protect the connector from dirt; ③ mount the new unit and reconnect; ④ start the car, run the ride-height reset / EAS initialization; ⑤ verify left/right height is even and check for leaks before a road test.

Q9: Warranty policy and shipping damage? 18-month warranty under normal use. For shipping damage, inspect within 48 hours of receipt and send photos/video — the seller arranges a replacement.

Q10: Service life and maintenance? Service life depends on road conditions and climate. Keep bellows clean and check for cracks during routine service; if the bellows crack or leak, replacing the complete unit is the most reliable and cost-effective solution.
